Warning to those port matching intakes

ibcnya · #1 02-02-2009, 09:30 PM

My 50 mile ride turned into a Epic Fail today. Half way there I was kicked in the nuts hard....bad part was I left the spare at home...

How many of you has this happened to? Looks like the result of thinning the metal out, heat and high vibration. I need a bracket to hold the intake/carb stable. Im gonna figure out how I can rig something to brace them off and keep the vibrations down. It should also control the foaming of the fuel in the float bowl some.

I would get one of the steel ones. The diameter of the tube is larger and they are much stronger even after matching the intake port.

Ive been looking for one but cant find a supplier....Ive got my spare on and even made a weak attempt at bracing the carb a little but i dont think its gonna help.

Maybe itll help, but probally wont. Im gonna keep trying different things though. Im thinking change the bend where i can drill a hole and run the float bowl bolt through it to.

A stiffer bracket may help. Is your spare ground on as well?

The regular engine suppliers should have the steels ones, no

I used to think the cast pups were the HiPo units....until I found out they are actually smaller ID. Now I guess here's another reason....

Interesting, never seen it happen.

I was trying to decide whether to port the aluminum intake, or the chromed steel. I noticed the steel seems bigger, and I figured it would hold up better. If you're going to port the aluminum version, it might be a good idea to have the outside of it welded up to add some extra material to compensate for what you're taking out.

Sorry to hear that happened on a ride.

Honestly I'm not sure how much a bracket is going to help. I think if you thin the material out too much, it will fail no matter what.

The new intake wasnt ported, I just put it on. It was a spare i had. To bad I didnt have it with me on my ride, but ill wait till I find a better chrome one before attemting to port again.

No my spare is completely normal aluminum cast. I pieced the broken one back together so you guys can see the extent of my porting. The only thing i can think of is a crack began at the top and worked its way around the seam...
